JITcompiled

JITcompiled refers to the process of Just-In-Time (JIT) compilation, a method used in computer programming where code is compiled into machine language at runtime rather than beforehand. This approach allows programs to optimize performance dynamically by translating high-level code into executable instructions only when needed, typically during execution or just before execution.

JIT compilation is commonly employed in environments that require a balance between execution speed and flexibility, such as virtual machines, interpreters, and certain high-level language implementations like Java, JavaScript, and .NET. In these systems, source code or intermediate code (such as bytecode) is first translated into an intermediate representation. The JIT compiler then converts this intermediate code into machine code during program execution, enabling the CPU to run instructions directly.

The primary advantage of JIT compilation is improved runtime performance, as it allows for optimizations based on the current execution context or data. Additionally, it provides flexibility, enabling programs to adapt at runtime, facilitate platform independence, and enhance security features. However, JIT compilation can introduce initial latency during program startup due to the overhead of on-the-fly compilation.

JITcompiling is distinguished from static compilation, where code is fully compiled into machine language before execution, and interpreted execution, where code is executed line-by-line without compilation. Overall, JITcompiled systems aim to optimize performance while maintaining the adaptability of interpreted languages, making them suitable for dynamic and performance-critical applications.
